28" tires are old British roadster-sized tires, largely unused on modern bikes currently in production (except for vintage styled Pashleys and other new-vintage bikes). Old English city bikes were usually equipped with either 26x1-3/8" (Raleigh Sports, later Superbe) or 28" tires (exclusively for their roadster models with more slack frame geometry).
That bike is a seriously great find, especially with the period-correct Brooks saddle. SHARE THE STORY! Where'd you get him???
+1 to the recommendation to deal with Harris Cyclery - they have the largest amount of info on those tires, and they maintain sheldon's site for cyclists everywhere (which is a darn good reason to support 'em).
